Recording MIG to accurately depict what the Welder sees is difficult but you've done as good a job as I've seen anywhere on KZfaq. Recording TIG during a Direct Current Steel weld is much nicer to watch. You've done a great job learning these processes and that's not easy at 50+. Keep up the great work Mark!

Thank you very much!

@Max-kc2rc Ай бұрын

The human eye (and brain ;-) just has quite some huge dynamic range. Much more than camera and screen can depict. If activate a strong additional illumination and spread the contrast more (gamma-correction) it might even closer depict what the welder experiences. Also gives a good Video: Hook up the welding trigger switch to a relay to active a strong halogen light-source ---> the welding videos will look even better.

4th weld was the nicest because the base metal temp increased with each weld allowing the cold settings to work better. Increase your volts and slow down on your travel speed.

Looks good. About the only way I can think to improve the image is a very bright flood light, to bring the rest of the image a little closer to the brightness of the arc.

Instead of a auto lens you could try a solid filter from Phillips-Safety, they are expensive but ive found, for eye balls atleast, that they are super consistent and give better clarity. they would probably help you with your own welding too. it just means that you are going to have to frame the shot and then mount the filter lense.

Hi Julia, it is quite an improvement on tape :)

@Michael-ze6oz Ай бұрын

The camera will correct the sensitivity to what it sees to an average of 18% gray (even with the filter). When you have a small bright spot surrounded with a large dark area, everything will be 'made' lighter. Dark area become gray, the bright spot much too bright (overexposed). Because the camera average the lighting. (Opposite: a small black object on a bright white surface: the camera will underexpose it. No detail of the black object is visible anymore and the white surface becomes grayer.) Use a manual setting instead of automatic, tune the balance and you will notice the difference. Good luck!, Greetings

@RotarySMP Ай бұрын

I used to shoot everything manual with the G81, but since I got the GH5S i typically shoot manual, with auto-ISO. However yesterday i set up two custom profiles with full manual, white balanced with the filter for showing the part, and stopped down to the arc.

I'm not convinced you really can tune 3d printed holes coming out undersized. Like it's just the result of the concave and enclosed plastic features shrinking as they cool. Any kind of software solution would probably have to be in the clever simulation realm and add alot of time to the slicing... but it's not too much of a hassle to just to manually add a percentage to the hole diameters in CAD, estimated through intuition and gumption, and manually clean up the ones you got slightly wrong.
